ARTIFICIAL-STONEMOLD.

SPECIFICATION forming part of Letters Patent No. 790,480, dated May 23, 1905. Application filed July 28, 1904. Serial No. 218,552.

To all whom t may concern.:

Be it known that I, EDGAR E. CROUCH, a citizen of the United States of America, and a resident of Topeka, Shawnee county, Kane sas, have invented a new and useful Artiiicial-Stone Mold, of which the following is a specification.

The obj ect of this invention is to provide improved means for molding artificial stone.

My invention consists in the construction, arrangement, and combination of elements hereinafter set forth, pointed out in my claims, and illustrated by the accompanying drawings, in which- Figure 1 is a plan showing one form of my improved mold closed preparatory to molding a block therein, the hopper or side boards being removed. Fig. 2 is a longitudinal vertical section .of the device on the indicated line 2 2 of Fig. 1, the sideV boards or hopper being in place and the hinges and fastening means being removed. Fig. 3 is an end elevation of the device. Fig. 4 is a vertical section of the device on the indicated line 4 4 of Fig. 2. Fig. 5 is a view of the outermost face of a removable bottom employed in my mold, also iliustrating the means employed to attach and support the cores for forming holes on the blocks. Fig. 6 is a planof the mold, the hopper being removed and a false bottom or pattern-plate mounted in the mold for the forming of an ornamental face on a block. Figs. 7, 8, 9, 10, 11, 12, 13, 14, 15, and 16 are detail views illustrating pattern-plates of various shapes employed for forming plane or ornamental faces on a block. Figs. 17, 18, 19, 20, 21, 22, 23, and 24 are views of various blocks which may be molded in my device through the use of the various pattern-plates illustrated.

In the construction of the mold the numerals 10 11 designate the sides, 12 13 the ends, and 14 the bottom. The side 10 is connected at one end to the end 13 by hinges 15, and said end 13 is connected to the side 11 by hinges 16. Theopposite end portion of the side 11 is connected to the end 12 by hinges 17. The sides 10 11 are parallel with each other, and the ends 12 13 are parallel with each other and cross and contact with the ends of the sides, respectively. A hook-bar 18 is fixed to one end portion of the side 10 and projects acrossthe otherwise free end ortion of the end 12 and is formed with a ook 19, adapted to overlie said end and bind it to the side. The hook 19 is formed with an outwardly-projecting lip 20, adapted to be engaged by a hook 21, pivoted to the end 12. It is the function of the hook-bar 18 and hook 19 to bind the end 12 to the side 10, and it is the function 0f the hook 21 and lip 20 to bind and lock the hook 19 to the end margins of the ends 1213 to permit grasp-l ing the bottoni for removal when the mold is inverted, as hereinafter described. A pattern-plate 24, in this instance formed with plane upper and lower faces,.is mounted within the mold and rests on the bottom 14. The pattern-plate 24 may be imperforate when it is desired to mold solid blocks' but in this instance I presume the making of hollow blocks, and hence show the pattern-plate formed with apertures 25 26 to receive and permit the passage therethrough of cores 27 28 on the bottom. The cores 27 28 may set square with the mold and b e secured to the bottom 14 by screws 29, 30, and 31 in each core. The screws extend through the bottom 14 and are seated in the cores, the screws 3() 30 in the centers of the cores, and the screws 29 29 and 31 31 on eitherside thereof. The screws are arranged in rows obliquely to the square of the mold, or the pattern-plate may be formed, as shown in Figs. 15 and 16, with the apertures 25l 26a in the plate 24a obliquely to the square of the mold for use with'cores set obliquely to the square of the mold, as shown in Fig. 6, and in such case the cores are fixed by the same screws set the same way in the bottom 14,

but arranged in a row transversely of the cores parallel with the sides of the cores. Thus by loosening two screws in each core said cores may be rotated on the central screws and reiiXed by reseating said two screws, as shown by dotted lines in Fig. 6. Pattern-plates 32 33 are mounted on the inner faces of the sides 10 11 and are detachably fixed to said sides, preferably by small nails, the lower margins of said plates resting on the upper surface of the pattern-plate 24. The pattern-plates 32 33 preferably form the front and rear 'faces of the block. Patternplates 34 35 are mounted on the inner faces of the ends 12 13 and are detaeliably secured to said ends, preferably by small nails, the lower margins of said plates resting on the upper face of the pattern-plate 24 and the ends of plates 34 35 overlapping the ends of the plates 32 33. Cores 36 37 may be xed to the inner face of the central portions of the pattern-plates 34 35, and cores 38 39 40 may be fixed to the upper face of the patternplate 24.

Referring to Figs. 17 and 20, it is the function of the cores 27 28 to form holes 41 42 in a block 43, of the cores 36 37 to form grooves or channels 44 45 across the ends of said block, of the cores 38 40 to form grooves or channels 46 47, connecting the end channels with the holes, and of the core 39 to form a groove or channel 48, connecting the holes. The blocks so molded are laid in the wall with the plane top of the block upward and the channeled ,bottom of the block downward, the various channels and holes in the various blocks cooperating to produce a single sinuous and checkered opening or interior in the wall. In molding a cornerblock, such as 43a in Fig. 18, the coie 37 is removed from the pattern-plate 35, and the core is removed from the plate 24, and said cores are attached to the pattern-plate 34 or 35 and the plate 24 in the positions shown by dotted lines in Fig. 1. In the adjusted positions the core 37 forms a groove or channel 45a in the inner face of the block and the core 40 forms a groove or channel 47"L in the bottom of the block and connecting the hole\42 and channel 45a. Various similar adjustments of the cores 36, 37, 38, 39, and 40 may be made to establish and produce various forms of wall cavities. A patternplate 49, Figs. 7 and 9, may be substituted for either of the pattern-plates 24, 32, or 33 and when so substituted will form an imitation-stone face on the block. The patternplate 49 preferably is made of a frame 50 overlaid by a face-plate formed of battered sheet metal, the indentations and creases produced in battering the sheet metal giving the desired pattern to the stone or block. In

molding a corner-block with an imitation stone face it is desirable at times to form an imitation stone end on said block, and this may be done by substituting a pattern-plate 51, Figs. 8 and 10, for one or another of the pattern-plates 34 or 35. The pattern-plate 51 preferably is made of a frame 52, overlaid by a face-plate of battered sheet metal, the indentations and creases produced in battering the sheet metal giving the desired pattern to the block. rlhe pattern-plate 49 can be substituted for the plate 24 only when a solid block is to be molded. It sometimes is desirable to mold ablocli 53 with aliipped face 54, and such end may be accomplished by substituting a pattern-plate 55, Figs. 11 and 13, for one or another of the pattein-plates 32 or 33, the hipped cavity 56 in the patternplate 55 giving the desired face to the block. ln molding a corner-block, such as 57, Figs. 21 and 22, it may be desirable to form a pyrainidal face 58 on one of its ends, and such result may be attained by substituting a pattern-plate 59, Figs. 12 and 1.4, for one or another of the pattern-plates 34 or 35, the pyramidal cavity 60 in the substitu ted plate giving the desired shape to the end of the block. By substituting various difierently-forined. pattern -plates l am enabled to produce building-blocks presenting any desired lace, in imitation of cut stone, uncut stone, and other material indefinitely.

In Figs. 23 and 24 l show a block 59 having holes 60 61, formed by thecores 27 28, Fig. 6, and notches 62, 63, 64, 65, 66, and 67, formed in its margins by cores 68, 69, 70, 71, 72, and 73, fixed to the side and end plates of the pattern of the mold. This block 59 is desirable in forming friezes, dadoes, aprons, and the like and preferably is made thinner than the regular building-blocks by placing a false bottom between the bottom 14 of the mold and a pattern-plate 74. rl`lie patternplate 74 then forms the face of the block and in this instance is illustrated as made up of squares 75, shaped to imitate stone, a central square having a plane face 76, the squares set obliquelyto the square of the mold, and triangular plane faces 77 between the marginal cores. Any desired face may be formed on the block 59 by substituting for the patternplate 74 a plate having a different and desired face. The sides 1() 11 of the mold are of less height than the ends 12 13 and lmttern-plates mounted thereon, and a hopper is provided and 'formed with side boards 78 79, resting at times on the pattern-plates 32 33 (or others substituted therefor) and formed with bases 8O 81, fixed to the side boards and extending into positions of rest on the sides 1() 1 1. End boards 82 83 are llixed to and connect the ends of the side boards and rest at times on the end pattern-plates 34 35, (or others substituted therefor.) rlhe side and end boards 78 79 82 83 are set obliquely to the sides and ends of the mold and flare outwardly therefrom to form a hopper above the mold the inner edges of the lower portion of the hopper being flush with the up er inner edges of the side and end pattern-p ates. Grooves 84 85 are formed in the end boards 82 83', a groove 86 is formed in the side board 78, and a slot 87 is formed in the side board 79 and base 81. A screed 88, preferably formed of sheet metal, is mounted at times through the slot 87 and is seated in the grooves 84, 85, and 87. The screed is employed to cut the surplus composition from the top of the block after the composition has been tamped in the mold and serves, in conjunction with the hopper, to lift the surplus material away from the mold and deposit the same in another mold or retain itl until the first mold is removed from the block. In the use of the hopper and screed I am enabled to save all the material and at the same time cut auniform and plane face on the molded block. After a bloclr is molded I invert the mold on a plane bed of sand,.release the hook 21 from the lip 20, move the side 10 outward, then move the'end 13 outward, then move the side 11 outward, and then move the end 12 outward. In moving the sides and ends of the mold outward the patternplates are moved outward and away from the block. When a hollow block is molded in the device, the bottom 14 and cores 27 28 are removed after the mold is inverted. In either event the after the mold is inverted and before the sides and ends of the mold are removed from the block.

- I claim as my invention- 1. A mold, comprising sides, an end hinged to and overlapping the ends of both sides, an end hinged to and overlapping the opposite end of one side and also overlapping the other side, means for locking said ends to said other side, a removable bottom, a pattern-plate removably mounted on said lbottom and embraced by said sides and ends, and cores on s aid removable bottom.

2. An artificial stone mold, comprising sides, an end hinged to both sides, an end hinged to one side, a hook-bar fixed to the other side and having its hook engaging the free end, a lip on said hook-bar, a hook pivoted on the latter end and adapted to engage said lip, a removable bottom, a pattern-plate removably mounted on said bottom and embraced by said sides and ends, and cores onl said removable bottom. l

8. A mold, comprising sides, an end hinged to both sides, an end hinged. to one side and overlapping the end of the other side, a hookbar fixed to said other side and having its hook engaging the free end, a lip on said hook bar, a hook pivoted on4 the latter end and 5.
